Law of sines: Which expression represents the approximate length of ?

Mathematics
1 answer:
Sladkaya [172]3 years ago
6 0
Law of Sines formulas and equations are used to solve the length of the sides of a triangle. Example a given triangle with sides a, b and c and given angles opposite to the sides are A, B and C. The law stated the following:
a/sinA=b/sinB=c/sinC
We can also solve the missing length of the third side once we are done solving the first and second sides of the triangle, this is called triangulation.

Find the measure of MNQ
xz_007 [3.2K]

Answer:

m∠MNQ = 158

Step-by-step explanation:

As it can be seen in the figure:

+) The measure of arc MQ = 91 degree

+) The measure of arc RP = 225 degree

As this is the circle, four points M, Q, P and R are on the circle, so that we have:

+) m∠RMP = 1/2. measure of arc RP = 1/2 x 225 = 112.5 degree

As N is on MP

=> m∠RMN = m∠RMP = 112.5

+) m∠ MRQ = 1/2 measure of arc MQ = 1/2 x 91 = 45.5 degree

As N is on RQ

=> m∠MRN = m∠MRQ = 45.5

In the triangle RMN, the total measure of 3 internal angles is equal to 180 degree, so that:

m∠MNR + m∠RMN + m∠MRN = 180

=> m∠MNR + 112.5 + 45.5 = 180

=> m∠MNR  = 180 -112.5 -45.5 = 22

As N is on QR

=> m∠MNR + m∠MNQ = 180

=> m∠MNQ = 180 - m∠MNR  = 180 - 22 = 158

So that m∠MNQ = 158

Number of tickets sold on day two = 25

Number of tickets sold on day three = 35

Total tickets sold = 23 + 25 + 35 = 83

Since they want to share it equally, each boy will have:

= 83/2

= 41.5
